Smarter flat iron choice- Solia or Sedu?

I am investing in my first quality flat iron. After much research, I am going with either a Solia or Sedu. My hair is past my shoulders, very thick, and somewhat wavy. With my cheap drugstore flat iron, it takes me 40 minutes to straighten my hair, on the highest setting, and it still is not pin straight. I could not achieve the sleek look I wanted with a drugstore straightener. So, I want my new iron to:

- take 20 minutes (or less) to straighten

- last for ATLEAST 3 years

- leave my hair sleek, soft, and healthy, and perfectly pin straight

- I cannot exceed $120 dollars ( I found irons on folica.com that are within this budget from both sedu and solia)

- should I go with the narrower, 1-inch straightener, or the wider 1-3/4" one?

Solia or Sedu: Which is a smarter choice???

thanks!

oh, and is folica a reputable website? I have never ordered from them.
